ln the accompanyingdraivings in which like reference characters refertolike parts, l() represents the outer casinglof the -lock having aflange 12. adapted for securing the casing I1() to the inner face ot' adoor, not 50` shown in the drawing. At. the opposite end of' the casing10 is provided a head 13, ivhicli forms the outer end of the lock andintended tobe exposed upon the outer surface of a doo..A The head 13 isprovided with apertures 14, which are occu ied by the push buttons orheads 16 "of tie push bars 17, 1S. 19, 20, 21 and 2Q, adapted foroperating the lock.

Within the casing 10 is l aninner easing 25 having a head 26 with anannular flange 2T, adapted to be detachably secured to the fiange 12, sothat the inner easing and the lock mechanism may be readily Withdrawnfrom the Casing 10, without removing the latter from the door for thepurpose of changing the combination of the lock when desired.

The'inner casing 25 `is provided with anv annular bearing 30. securedtherein, to which bearing is secured a disk 31 forming a bearing. Thecasing is also provided with a disk y324 secured in said casing,formingr a bearing; and a longitudinal bearing is secured between thebearings 3() and 32. Said bearings form supports or guides for themechanism 'forming the lock` more fully hereinafter described.

The push bars 17, 18, 19 and 2O are adapted for operating the tumblerblocks and are all of similar construction. therefore the.

.following description ot one. .will apply to4 the duplications ot theparts. A plurality of push bars is provided for the purpose of providingdifferent combinations controlling the lock mechanism. Q

The push bar 19 is shown in Fig. 1, is vslidably mounted in the hearings30 and31 and 4has a portion which is ot rectangular cross-section toprevent its rotation' in said bearings.` The push bar 19 carries apushbutton 16`at one end which projects through the head 13 at one end ofthe easing 10 andv adapted to be operated with .the tingersby pushingthe button 16 against the action of a. spring 37. into the operativeposition, and when released the spring'V 37 will return the bar 19 toits normal position. which position is controlled by a stop 38 ou thebar 19. f 'The push bar 19 is provided with a pavvl 39, pi'voted upon ashaft 40, secured in the har 19, and held in operative position by aspring 41 secured on said bar 19. The pawl vse 39 engages a tumblerblock 42 mounted upon l a body bar 43, which latter is slidably mountedin the bearings. 31 and 32. 4The body bar 43 is mnved by a. spring 44,into a normal position 'with the one end of the bar 43 against the head13 of the easing,

which letteracts iis a. stop to limit the uiorenient in one direction.The body bar i3 has a circular portion surrounded by the spring 4-1, undu flut ppi-tion which loruis u shoulderei a'.i;:iinsty which the spring'i4; acts. The fiat portion of the bur itl prevents the bur from rotatingin the bearing` 3l.

The tumbler bloeit 2 is udjustubly mounted upon the bur 43 and sindblot-lg 4.2 is provided with teeth 1.8 :idup'ted ,to he engaged by thepuiil 40 adapted tor moving the block 42 :ind the body bur tillongitudinzilly.

A bolt-controlling-member 5:2 issecured upon :i iongitudinal shut't 53 positioned centrally ot' thecasing 10. Said shaft 53 is rotatably mounted in the nearing 32 :itd oneend thereof, :1nd the other end is supported upon the portion 55 ot' thecentral push rod 21, which hitter. is allowed to nieve longitudinally inrelation to'v the shaft 53, :is said portion 55 `is adapted toire-elyenter the recess .5G formed in u. shaft The boit-controlliiig-member 52is in the form of :i dishhaving slots 57 formed in. its periphery inparallel relation with the axis of the shaft 53. rThe rib 49 on thevblock 42 is adopted to occupy the slot 57 inthe disk and hoid the diskand shaft 53 against. rotation. When the block 42 is moved by the pushbnr 19 until the transverse recess 50 formed' through the rib i9 of theblock is in register with the disk 52, the disk will be tree to rotate,thus releasing the bolt-controlling-member 5:2I and permitting the bolt64 to be operated as here inefter described.

The toggrieplute 81' has e.boss 91 secured centrally thereon. Suid boss is provided with :inaperture throughA which .the rod 88 freely passes. When the toggle-plate8i is 'swung in either direction from the center liuc of the pushhnr 22,the bossy 9i will engage either ofthe springs 86 or 87, placint,r thesame under' sutlicient tension so that when the push bar Q2 is signinreleased, the

phites 89 und 9i) springs SG or ST will tend-to swing the toggle-plateSl to its'central position as shown in Fig. 4. It will thus be. seenthat, when the tumbler block 42 is moved so as to bring the recess 50 insaid block42. into register' with the bolt-controlliiig-member 52. thelatter and the shaft :1 will thus be released. aud the bolt (S4 muy lbe,shifted by pressing the linger against tlic'butt'on 16, carried b v thepush bar 22.

'l`he tumbler block 42 is adapted to be moved by the pawl 39 whenthepush bar 19 is moved in\`vardl by pressure. upon thc button 1G on thebar 19. .1 lat-:h pawl. 92

. is pivotally mounted upon a projecting lug 93 formed on the bearing30. Said latch pawl 92 is adapted to be moved into engagementwith jtheteeth 48 of the block 42 by the aetionot a spring 94. Said pawl92'automatically engages the teeth ofl the -block 42, as it is advancedby the pawl 39,

and prevents the spring 44 from moving the body bar 43 and the block42-'towards its -normal position when the pawl 39 1s released .fromengagement with the teeth 48 of the block 42. Thus it vwillbe seen thatthe block 42 and the bodybar 43 may be advanced `intermittently bypushing the pawls 39 and 92 and allowed to ret-urn to its,

push bar"19 b v linger pressureon the button 1G, secured to said-bar 19.

The tumbler block 42 and body bar 43 may be released from engagementwith the normal position through the action of the spring 44, by means'of releasing mechanism,

consisting of the push bar 21, slidably mounted in thevhearing'l landtelescoping at its other end with the shaft 53, as above described. Uponthe push bar 21 is secured a hub 96 of adruin. consisting of spokes 9Tand a. rim 98. The spokes 97`1of the drum are arranged to pass freelybetween the push bars as shown in Fig. 7 and thus support' the rim 98 ofthe drum in alignmentv witlivthe pawls 39 and 92. The pawl 92 operatesthrough theraperture 99 in the rim 98 of the druln so that said pawl 92may project through the druln and' engage the teeth 48 otl the tumblerblock.- lVhen the linger is pressed against the button 1G. secured tothe push barl 21, the drumis moved so that the rim 9S engages the pawls39'and 92 simultaneously and,lifts sa id pawlsI out of engagement withthe lteeth 48 of the block 42. thus allowing the spring 44 to move thebody bar. 43 and the blok 42 back to the original position. as shown inFig. 1. 'hen the push bar 21 .is again released the spring 100will'igeturn the push bar 2.1 toits normal positon moving the rim 98 ofthe drum out ot' engagement-with the pawls 39 and 92', allowing them toeu-v gage the teeth ot' the block 42.

To permit the combination of the lock to be changed, the tumbler block42 -is ad formed.

The screw 102 is threaded into ar lug' 104 formed upon one side of thetumbler block 42. Vl'heu it is desired to change the combination of thelock the inner casing is removed from the outer casing 1t). The entiremechanism ,of the lock is mounted withinv the inner casing 25, so thatit may readily be withdrawn from the casing 10. lVhen so withdrawn," theadjusting screws 102 are accessible through holes 105 formed in thebearing 31, as shown in Eig. 6. By rotating the screw 102, the block 42may be moved upon the body bar 43 into ditl'erent positions, so that the-block 42 will have to bemoved different distances by the pawl 39, to beput into a :posit-ion to allow the transverse recessO, of the block 42to register with the bolt-controlling-menrber :32 and allow the latterto rotate and thus release the bolt 64. 'Each movement of the push bar19 by a pressure of the finger upon the button 16,' securedlto said bar,will cause the awl 39 .to move the block 42, one tooth. y adjusting theset screw 102 to a position which will bring the recess into registerwith the disk 52, when the block 42 Ahas been moved, one tooth, it willbe seen that o' e pushing movement of thefbar 19 will bring the block 42into a position to release the disk 52,01' the ladjusting screw `102mayle set ,so that two, three or 'more teeth will have/'to bev engagedby the pawl 39, upon successive movements of the bar 19 to bringtheblock 42 into a position to release the disk 52. As shown in Fig. 1an extra tooth 42a is provided upon the block 42 so that if the pushbar19 is pushed too many times the recess I52 will pass beyond the4position necessary to bring it into reg- .ister with the disk v52, sothat the rib 49 will again lock the disk 52, and prevent the lock frombeing released. By having two or more push bars and tumbler blocks, suchas shown in Fig. 7, in which four push bars 17, 18, 19 and 20 are shown,which are all similar to the push bar 19, and having similar operatingvarious combinations may be obtained by adjusting the differentL tumblerblocks to different' positions upon the body bars, so that a differentmovement, or different oomvbinations, will beV required for moving each`of the different push bars before the bol-t- 'eontrolling-niember 52will be free to rot-ate eral tumbler blocks.

mechanism as above described,

through the lrecesses 50 formed in the sev l The operation ofmyinvention is as :t'ollows: The different. tumbler blocks are first setby'. the adjusting screws 102, .so ,that a different number of movementsItvill be required by the vdiflerent push bars to bring: the parts intoa position to release the lock. 'lhe inner rasinr is" then seeured inthe outer easing: with the push buttons 1G projecting and exposed beyondthe head [2l ot the outer casing: l0. By pushingr the push button 1G. tomore the, push bar 21 inwardly the rim 9S ol' the drum will release thepawls` Ill) and 92 from the several tumbler blocks 42e thus allowing thetumbler blocks and the bod;v bars to return to their normal position bythe action of" thesprinns 14, thus looking! the bolt-eonlrolling-member59, by the tumbler blocks. so that the membeu can not rotate and the-boltltll will be held in eitherc the incl-:ed or unloz'ked position. Torelease the lock the push bars 17, 18, V19 and 20 are each pushed therequired nurn-I ber ot times) aeeording to the eou'ilmuition .into whichthe tumbler blocks are set. These successivemovements will bring all oithe tumbler blocks into a position so that the recess o() will registerwith the bolt-controlling-member 52, which latter is thus released andJfree to be rotated. 'lhe push bar 2Q is now moreel inwardly bypressing' u )on the button 1l). secured to said bar 212. wiieh movementslides' the sliding plate 78 and the toggle-plate 8l inwardly so thatthe latter will press, against a finger T5 or 76. on the pivot plate G7,and turn the pivot.

plate (i7 about' the'pivot pin 68 sullieiently to allow the spring toslide the bolt 64 into the opposite position. Each movement ot the boltG4 will swing.;q the pivot plate (3T into a position so that either thefinger A or the finger 76 will be in a position ready to be engaged bythe toggle-plate 81. and successive. Wishing movements upon the push bar22 will shilt the bolt (il into opposite positions. 'l`o again lock theparts so that the bolt.- tl-l can not be moved, it is only necf essaryto press the lmtton 16. secured on the push bar 2b so that the rim 98 ofthe.

drum will release all the lpawls 39 yand 92 and allow the tumbler blocks42 to return to their normal positions' and thus lock thebolt-controlling-member and the bolt. 64 against further movement.

ln the p'tesent embodiment of my` invention. I have shown the improvedlock mechanism arranged in a cylindrical barrel or easing. whereas themechanism may be ar- `ranged in a. casing of rectangular cross-seeton orin flat formation adapt-ingr the saine tfor a pad lock as illustrated inFigs. tl to 12,

which changes may be readily nuule. \vithoutV departing Jfrom the seopeot' my invention.

The embodimenty oll my invention disclosed in Figs. 8 to l2. eonn'nisesteleseoping casinos 110 and 112 of'flatreetaufrular tormation. in whichthe pushbars 115. the latch operating bar 116 'and tlie'releasing bar117 nre arrangedlin the same plane, or approx-- 12T formed througghwhich tumbler blocks 130 are `movl able bythe push bars 115. Each block130 is provided with a recess 131 which may be brought into registerwith the bolt-controL,

ling-member 1:25, thus releasing the latter from lockingr engagementwith the tumbler blocks 130.

There is a tumbler block 130 associated with eaeh ofthe push bars115,'whi'cl1 are duplicates. thus only one is shown in Fig. 8 (rt-thedrawing. The push bar 115 has a paul 1533 pirotally mounted thereon`adopted for engaging -with ratchet teeth 132 'formed upon the tumblerblock 130. By pressing' `Said member 125 hasA the button and moving thepush bar 115 ini wardly against the spring' 135. the paivl 133 will morethe tumbler block 130 in 'relation to the.bolt-controlling-member 12.Vinto a position to release the latter. providing the bur 115 is movedthe proper number 0f times according to the combination at which theloelt set. flateh pawl 123i' is pivoted upon a bearing lill formed onthe casing 112, and prevent-s the return niovement lot the tumbler block130. when the tumbler block is moved by the pawl 133.

vThe tumbler block 1230 is morably mounted upon abody bur 13S and may beadjusted into different positions upon the 'body bar by means of a setscrew 140` movable with the body bar. By means of said set'screw thetumbler bleek may be set in different positions upon the respective bodybar s0 as toehnnge the combination formed by the several different.tumbler blocks of the lock, in the manner above described. bar 138"'isslidable longitudinally in bearings'ltl und 142 forme-d upon the casing112 and is movable to a normal position by ineens of a, spring 143positioned between When all of 'the tnn'xblerblocks. been Il moved. bytliepush bars 115 into a position to release the bolt-oontrollingfmember125y the, latter may be movedlongitudinally 'in the bearings 126 bvmeans of thelateh ope-rating" bar 116` which is also4 movable by inegerpressure npona button upon the-bar y 110.

The bodyl fao tbe bolt-controlling-member 125, so that when the ,lever147 is operated by the push bar 116 and rotated about the pin 148, thebolt-controlling-member 125 will be' moved longitudinally in thebearings I126 by means of the pin 150, being engaged and acted upon bythe lever 147. T he tree end of the lever 147 engages a pin 1"2 upon thehitch bolt 153 and is adapted to move .said bolt out ot Vengagement withthe shackle 155, which is pivotally mounted upon a pin 156 secured inthe casing 112.

When it is desired to more the parts intolocking position, the releasebar 117 may be moved inwardly by linger pressure upon the button uponsaid bar 117, so that a crossbar 158 secured upon'thev inner end of thepush bar 117, will be moved under all of the pawls 133 and 137 and lit'tsaid pawls out of engagement with the teeth 132 of the tumbler blocks180, thus permitting the springs 143 to return the tumbler blocks 130and body bars 138 to 'their normal positions,

in which the tumbler blocks will again enter Yso the recesses 127 formedin the bolt-controlling member 125 and prevent the latter from slidinglongitudinally. Unless said member 125 is released from engagement withthe tumbler blocks and free to more longitu-` dinally, the pin 150thereon, will prevent the latch controlling lever 147 from moving aboutthe pivoted pin 148, thus the operating bar 116 will be automaticallylocked.

All the parts ot the lock mechanism are carried upon the inner casing112, which may be withdrawn from the outer casing 1i() by removing ascrew 160, which extends through the opposite walls of both casings, asshown in Fig. 9.v The screw 160 is provided with a Hat surface 161.against which the latch controlling lever 147 is held-and prevents saidscrew from rotating when the loclmechanism is in the locked position,therefore it is necessary to shift the lock mechanism into the unlockedposition before said screw 160 can be rotated and removed from thecasin'gs. lVhen the casings are separated the heads of the adjustingscrews 140 are accessible through the open end of the inner casing 112,thus permitting said screws to be turned for setting the tumbler' blocksinto different positions upon the body bars and thus change thecombination of the lock.
